To all whom it may concern:

Be it'known that I, CURTIS C. CARTER, a citizen of the United States,and a resident of Bluffs, in'the county of Scott and'State of Illinois,have invented a new and Improved Regulator for Incubators, of-wh1ch thefollowing is a full, clear, and exact description. I V

My invention" has. for its object to provide an incubator having memberswhich may be opened to quickly cool and change the air in the incubatorwhen the temperature in the incubator rises above a predetermined point,the means provided' 'for opening the members also serving to open adamper connected with the incubator heater.

Another object of the invention is toproride the incubator with a flueconnected with the heater adjacent which there is a water leg connectedwith a water jacket disposed around the heater, it being possible toopen communication betweenthe interior of the water leg and theincubator when desired, for increasing the moisture in the incubator.

Still-other objects of the invention will appear in the followingspecification n which the preferred form'of my invention is described.

In the drawings similar reference charac-- ters denote similarparts inallthe views, in which i Figure 1 is a sectional view on the line 11 ofFig. 2; j Fig. 2 is a view on the line 22'of Fig. 1;

Fig. 8 1S a sectional view on the line 3-3 of Fig. 1, and

Fig. dis afragmentary 560131011511" view showing the connection of thethermostat with the operating lever.

By referring to the drawings, it will be seen that the incubator isprovided with a casing 5 having an opening 6 in its 'bottom 7, and anopening 8 in its top 9,- a member 10 being provided for closing theopening 6, and a member 11 being provided for closing the opening 8.These members 10 and 11 are connected by rods 12, so that when themember 11 is raised, it will carry with it the member 10, therebyopening the doorways 8 and 6 at the same time. A bracket 13 is mountedon the top 9 of the casing 5, and this bracket 13 serves as a fulcrumfor a lever 14, an arm 15 of which is articulated at 16 to the door 11,the other arm 16 of the lever being provided with a counter perature. Idrawings'the flue 28passes out of the incuweight 17, it being possibleto adjust this counterweight 17 on the arm 16 of the lever j Patentedea. 23,1917.

1% as may be desired, in a manner readily understood. Disposed on abracket '18within the incubator casing 5, there is a thermostat 19, arod 20 being secured to the thermo stat 19, the .rod 20 passing throughan opening 21 in thecasing 5. Mounted on the rod 20,-there is a cap 20",which is disposed in a recess 20 in the arm 15 of the lever 14:. It

will be understood that when the thermostatexpands, it'will operate thelever-14:, with the assistance of the counterweight 17, to'raise themembers 11 and 10, thereby lowering the temperature of. the interior ofthe incubator casing *5. by 'aermitting *the passage-of cool and freshair to the incubator. The top of the rod 20 is threaded and meshing withthis thread there is" a nut 20 which may be adjusted up or down to raiseor lower the cap 2O as may be desired, the p cap .20 being supported onthe 11115202 The incubator is heated by a heater; which maybe a lamp 22,which I showjin the drawings mounted on a bracket 23 secured to the sideof the casing 5. Disposed around the upper portion 2 1 of this lamp 22there is a water jacket 25, from which eX.-

tends a water leg 26, this water leg 26 passing through an opening 27 inthe'casing 5, and being disposed within the casing. .Dis-" posedabovethe water leg 26 there is a flue 28 "which also passes through theopening 27- in the'c'asing 5, this flue extending from the passagearound the lamp22 formed by the innerwall 29 ofthe' water'jacket 25.This passage formed by .the wall 29 is: normally closed at its top bya'da'm'per ,30, and

air isadmitted to this passage formed by thewall 29'aroundtheflanip 22.fIt' will be seen that when the damper 30 is closed all' the heated airdirected upwardlybv the lamp'willpass through the fluei.28, and that uthis heated air will assist in keeping the water in the waterleg'26 atthe proper tem 1 As indicated in Fig. 10f the which are secured to a rod3% disposed in earings 35 in the walls ofthecasing 5, a handle 36 withwhich the rod'34eis provided being outside the casing.

As has been stated, the thermostat, by means of the rod 20, the leverlei. and the counterweight 17, serves to open or close the members 11and 1-0. Thisthiermostat l9 also serves to raise and lower the damper80, thesaid damper 30 being connected by alink' 37 withan arm 38 of alever 39-,1the lever- 39 beingfulcrumed at 40 to a-bracket'Ll mountedonothe top ,9 oizthe casing'5, the saidvlever 39- being also connectedwith the arm 15 ofthe: lever "le-bymeans'of a link: e2. It. will,therefore, seen that when the temperature, in the incubator. casing 5rises beyonda predetermined point, with the expansion of the thermostat19, the

which have been described, to close the doors 11. and 10, and'also thedamper 30. When the-damper 30 is raised the-a1r will move in the flue 28in the direction of thelamp r and the fiueZS will be cooled by the coolair entering" the flue;

It will .be. seen that the water leg 26' has branches 26?, which extendlaterally" and then, at 26", substantially parallelwithth'e main waterleg-26, andthen back againat 26?, toconnect withthe main water leg 26,
